Thirty-two varieties of common and durum wheat, hordeum, barley, and tritordeum collected over two harvesting years (2020 and 2021) were investigated for the presence of multiple Fusarium-related mycotoxins in asymptomatic plants. DON, 3-AcDON, 15-AcDON, T-2, HT-2, and ZEN together with the emerging mycotoxin ENN B and the major modified form of DON, namely DON3Glc, were quantified by means of UHPLC-MS/MS. Overall, DON and ENN B were the most frequently detected mycotoxins, albeit large inter-year variability was observed and related to different climate and weather conditions. Straws had higher mycotoxin contents than kernels and regarding DON occurrence tritordeum was found to be the most contaminated group on average for both harvesting years, while barley was the less contaminated one. Emerging mycotoxin ENN B showed comparable contents in kernels compared to straw, with a ratio close to 1 for tritordeum and barley. Regarding the occurrence of the other evaluated mycotoxins, T-2 and HT-2 toxins have been spotted in a few tritordeum samples, while ZEN has been frequently found only in straw from the harvesting year 2020. The data collected confirms the occurrence of multiple Fusarium mycotoxins in straws also from asymptomatic plants, highlighting concerns related to feed safety and animal health. The susceptibility of Tritordeum, hereby reported for the first time, suggests that careful measures in terms of monitoring, breeding, and cultural choices should be applied when dealing with his emerging crop.

Tritordeum is the new cereal derived from crosses between the wild barley Hordeum chilense Roem. et Schultz. and either durum or bread wheat, resulting in hexaploid and octoploid tritordeums, respectively. The success of tritordeum as a crop depends on the effectiveness of its breeding programme. In this work, new advanced tritordeum lines are screened for grain carotenoid content and disease susceptibility to analyse the impact of the current breeding strategies and to identify their strengths and putative limitations for future challenges. We conclude that selection for grain carotenoid content, the main strength for the tritordeum commercialization, should be reinforced not only by using the diversity of H. chilense but also incorporating beneficial alleles from durum wheat. Furthermore, genes for stem rust resistance from the A and B wheat genomes must be incorporated into tritordeum breeding programme. Finally, when selecting for threshability, tritordeums without chromosome substitutions should be preferentially selected using a marker‐assisted selection approach.
